Pulling large gauge wires through conduit bodies and conduit around garage door.


I am planning a project that will include running some conduit over a garage door (Is this allowed?) then outside and underground to a mobile home. I like the cleaner look of a conduit body to exit the garage and go underground. But how hard is it to pull larger gauge wires through these conduit bodies? Using 2" schedule 80 with 4/0-4/0-2/0-#2

My plan is currently go above the garage door and then down exit the garage and have my conduit body and expansion coupling right together go underground to the mobile home and do the same thing with a expansion coupling and conduit body then to the other end of the mobile home up through the floor and through a wall to the new sub panel.

Any suggestions because this is just in the planning stages right now.

Use individual conductors, they are easier to pull into conduit.

Must have less than 360 degrees of bends.

Just a question, why would it have to go over the garage door in the first place? Are you putting another panel in the garage? I would make it so right where it comes into the garage is where a sub panel would go, but again I am not sure what you are doing.

Main panel is in the garage and I need to get on the other side of the garage door so I can go outside and into the mobile home.

Yes that is what I am using individual conductors.

That seems really hard to get around that less than 360 degrees of bends. I need two 90 elbows in the ground and one to get under the mobile home and one to get up into the home. Plus there will have to be either two or three in the garage.

Standard mobile home feeder is actually 4/0-4/0-2/0-#4

AL sorry I should specify.

Do LB conduit bodies count towards the 360 degree bend rule.

Ok then I seem to be ok with that because I have three 90 elbows on one side of the two LB's and three on the other side. With two elbows between the LB's

I don't know why they consider the #4 enough but I am planning to use #2 do you think that is enough?

Yes do you think I should go up to 4/0 neutral? And if so why?

Yes I remember his response was just willing to listen to other ideas and started this topic to make sure my idea of going above the door and using all those elbows would be ok. Just have to figure out about how I want to do the grounding. Thinking just a straight run of #6 or #4 from the sub panel to the two rods. Any ideas?

Mobile homes do not require ground rods. You install them at the service/disconnecting means, not at the home.

Since I already have a bunch of rods in my garage. I may just drive a couple. Do I also need a bond to a water pipe and the mobile home frame?
